The storage of breast milk should be noted from many aspects, such as the applicable storage container, storage temperature, labeling date and amount, etc., as follows: 1. Operation method: 1. Applicable storage container: According to the size of your baby’s appetite, try to choose a storage container with the right capacity to avoid wasting too much frozen storage. Make sure the container is clean and dry before storage, do not fill it too full each time, and choose a well-sealed and sterile milk storage bag or glass milk storage bottle; 2. Storage temperature: breast milk can be stored for about 4 hours at a room temperature of 20°C. Do not leave breast milk for more than 1-2 hours in summer, as it is easy to breed bacteria; it can be stored for 2-4 days in the refrigerator freezer at 0-4°C; it can be stored for 3-6 months in the freezer; 3. Mark the date and amount: Write down the date and amount of milk on the day of sucking, one bag is about 90-120ml, you can also freeze 30-60ml for storage in small portions so that when the baby does not drink enough, it can be used for rehydration to reduce waste, be sure to put a prominent label on the surface of the container each time you store it, indicating the date, and in principle, consume the earliest batch first. Second, note: 1. In general, it is not advocated to freeze breast milk and then thaw it for babies, which cannot guarantee the quality and nutrients of breast milk. If you need to freeze it, you should drink it as soon as possible within the shelf life; 2. When thawing breast milk, do not use boiling water directly, but rinse the sealed bag with cold water first, then gradually add hot water until it is completely thawed and raised to a suitable temperature, or place it in the freezer to slowly thaw and degrade the ice. Do not directly heat breast milk with stove fire or microwave oven to prevent high temperature heating from destroying the nutrients in breast milk.
